There's a lot of wild talk about the effects of acid, but one thing you won't see is aliens. For the first-timers let me say this: the trip is nothing like what you expect of it and it can be a pretty rough ride. I'll admit that acid eventually scared the crap out of me after it was a long time obsession of mine. When you close your eyes that's when you can 'see' all sorts of things that are both visual and emotional. There is no escaping long as the trips lasts and in the beginning it is like a roller-coaster you wish you could go off but you can't. After you have taken it once you can never go back, like the pill from the Matrix. That's how i see it and i probably won't take it again but since i already took acid i might as well do it again since the impact will never be as heavy like the first time.
